Phal has no roots but has air roots HELP

[EkkieMom]

I have had this particular Phal for about two years. Recently I noticed that it's leaves were wrinkled and limp. I started to read on this forum and pulled him out of his pot to take a look. The pot the plat was in was one of those soft plastic pots and was in moss. Thinking maybe the roots weren't getting air I cut off the plastic pot a carefully pulled off the moss. To my horror there are NO ROOTS! It does have 4 leaves each between and 10 inches long. There is one new leave just coming out. It has 6 what I call air roots that were growing outside the moss. I have apologized to the Phal. What should I do now. He is sitting on some dried moss at the moment. Am I supposed to repot using bark and bury the air roots because they are really root roots?
